need help?

I spent 8 and a half hours recording myself drawing and sped it up so
the video is now about 13 minutes. I tried to upload it to YouTube, and
it kept crashing. I'm now trying to download it to my computer as a file
that can go on YouTube, but the upload keeps randomly pausing at 70-90%
through and I've waited for about an hour but nothing happened. It's
really frustrating. Does anyone know why this happens? Is the video too
fast?
